I CAN'T FIND MY IPHONE

As always my phone has the find my iPhone app running at all times but my phone can't provide it's own hotspot (Wi-Fi). I logged on to the app on a different device and it can't locate it. I tried the play sound but I'm not sure it's working cuz my iPhone always has earbuds attached. Please help! I'm not sure if I dropped it while getting into the car, it fell in the cracks, or I just misplaced it in my home. (I'm not sure about that last one cuz my phone gets Wi-Fi here).Is there any way to find it! And please don't tell me to backtrack it cuz I already did that.

I'M FREAKIN OUT!

Added (1). Btw, I don't hav any phone service cuz I didn't hav the money so the calling option is out. I hav lost so many things (I hav a list) so this isn't the first time I lost it. Also, if I bring it up in my family, it would cause a ruckus, brothers looking everywhere, dad trying to find it by asking questions, and mom with a "I told you so that she wasn't responsible enough" look at dad.

Call your phone number from someone else's phone so you can track your phone through the ringing, though would only be an option if you're sure it's in the house.

AHH GUTTED! This happened to me. My 3G was off and it wasn't connected to Wi-Fi. I just kept ringing and ringing - no luck! Luckily got it back a week later - the taxi firm I left it with had it.

Log onto your iCloud, see if you can locate its last whereabouts! Keep pressing the sound button and put a lock on your phone! (Options are provided) Keep ringing it and pray someone kind finds it and hands it back to you! If it is contract phone - ring up your provider and get it blocked NOW! Prevent the next person using it. Is it possible to ask your provider if they can locate the sim? No harm in checking! Also just keep refreshing the "locate my iphone button" - HOPEFULLY if someone found it and wants to play "finders keepers" will be stupid enough to connect it to Wi-Fi.
Oh my gosh. Feel so bad for you! Hope you have insurance! If not totally gutted for you x

You could check in at last places you went or into shops which were near by. You could ask around or maybe go to the nearest station you never know you might find it! But i would most probably check my house.call friends and tell them to help. I wish you luck i hope you find it, I know the pain all to well
